Detailed explanation-1: -Reaction time is the time interval from the instant of stimulation to the instant of a voluntary response. All responses result from the formation of impulses by stimulation & the transmission of these impulses along neurons to effectors that bring about the response.

Detailed explanation-2: -The speed of a reflex is greater than that of a voluntary reaction, due largely to the relative complexity of the neural pathway for a reaction (Fig.

Detailed explanation-3: -Reaction time (RT) and movement time (MT) are measured in two conditions, a key-press and a key-release condition. The latter makes a greater demand on perceptual feedback than the former. RT increases in the key-release condition and a fraction of MT denoted key-press time (KT) decreases in the key-press condition.

Detailed explanation-4: -Voluntary action are under control of ones will, whereas reflex action are spontaneous involuntary, nerve-mediated activity produced at the unconscious level by stimulating specific receptors. The former is under control of brain, whereas in the latter spinal cord is involved.
